Concurrent Therapy Productivity Calculator
This Concurrent Therapy Productivity Calculator is built for PT, OT, and SLP clinicians who see patients concurrently or in groups. Enter your start time, billable minutes, and target, then add concurrent or group crediting if your facility counts those minutes differently. For the simple 1:1-only case, see the standard Productivity Calculator instead.

About This Concurrent Therapy Productivity Calculator
This calculator extends the standard start-time productivity calculation to cover concurrent and group therapy sessions, where clock minutes don’t always equal billable minutes on a 1:1 basis. Enter your 1:1 billable time, your productivity target, and — if it applies to you — the length of a concurrent or group block and how your facility credits it (full, split, or a custom factor). Calculator inputs are intended to be processed in your browser and no login is required. See Privacy Policy for details.
Who built this & how accuracy is maintained
Built and maintained by Umer Farooq, founder of Therapy Productivity Calculator. The Medicare concurrent/group definitions and the PDPM combined-minutes limit referenced on this page are checked against CMS billing guidance (linked in Sources below). The calculator’s full, split, and custom productivity-credit options are modeling choices for an employer or facility’s internal productivity system; they are not Medicare-defined productivity-credit methods. The arithmetic is verified with worked examples before publishing. Always confirm the productivity method your employer uses and the billing rules that apply to the patient and payer.

Why Use This Concurrent Therapy Productivity Calculator
A standard productivity calculator assumes every clock minute maps to exactly one billable minute. That assumption breaks the moment a clinician runs a concurrent or group session, because how those clock minutes count toward an employer’s productivity metric may depend on that employer’s internal productivity-credit method. The full, split, and custom options below model those internal methods; they do not determine what Medicare or another payer will reimburse.
This Concurrent Therapy Productivity Calculator keeps the simple 1:1 case front and center — leave the adjustment box unchecked and it behaves exactly like a standard start-time productivity calculator. Check the box, and it gives clinicians who do run concurrent or group sessions a way to model credited minutes against their actual target, see the real clock-out time that results, and get a rough planning flag when entered SNF Part A concurrent/group clock minutes appear to exceed 25% of the minutes entered in this calculator. That flag is not a PDPM compliance determination for a resident’s full PPS stay. If your facility tracks Part A stays closely, pair this with a PDPM Therapy Productivity guide to check the combined minutes cap directly.
How This Concurrent Therapy Productivity Calculator Works
This tool models how a facility may credit concurrent or group clock time inside its own productivity calculation. It does not convert an internal productivity factor into Medicare-billable units or determine reimbursement. Enter the internal crediting method your employer actually uses, then the tool folds those credited minutes into the productivity estimate.
Log 1:1 time
Start with your simple, one-on-one billable minutes — the part of the day with no crediting question attached.
Add the concurrent/group block
Enter the clock minutes in a concurrent or group session, how many patients you saw, and which crediting model your facility uses for it.
Get adjusted productivity minutes
Split credit leaves it at the raw clock time, full credit multiplies that block by the number of patients, and custom factor applies the multiplier your site uses.
Solve for end time
Divide your adjusted productivity minutes by your target percentage to get the total paid time required. Add that to your start time to get your ideal end time.
How to interpret your result
Compare the calculated result with the productivity target and crediting method actually used by your employer or facility. This calculator does not apply a universal “good,” “average,” or “poor” productivity range because expectations vary by setting, discipline, employer policy, payer rules, and calculation method.
Good to know
- SNF / Part A (PDPM): concurrent therapy is typically defined as two residents in close proximity to one another but engaged in different activities, while group therapy is typically defined as two to six residents engaged in similar activities. The combined total of concurrent and group minutes is limited to no more than 25% of therapy received for each discipline under PDPM.
- Outpatient / Part B: CMS describes group therapy as simultaneous treatment of two or more patients when the therapist is dividing attention or giving shared instruction; group therapy is reported with 97150 for PT/OT in the cited CMS scenarios. Do not assume an SNF concurrent-therapy productivity rule applies to Part B.
- SLP: Medicare group-treatment rules can depend on setting and the Medicare Administrative Contractor (MAC). ASHA notes CPT 92508 for speech, language, voice, communication and/or auditory-processing group treatment, while other disorders may depend on the applicable LCD. Verify the current payer/MAC rule rather than assuming PT/OT rules apply.
- Related resources: review the Concurrent & Group Therapy Productivity Guide and PDPM Therapy Productivity guide for additional context.
These crediting rules change over time and vary by payer, state, and facility, and are subject to interpretation. This tool is for personal planning and estimating credited minutes — please verify current policy with your billing lead.
Concurrent Therapy Productivity Calculator: Worked Examples
Three examples showing how the crediting model changes the adjusted minutes and the clock-out time.
5.5 hrs 1:1 + 30 min concurrent, full credit
“If I have 5 hours 30 minutes of 1:1 time and a 30-minute concurrent session with 2 patients, and my facility gives full credit per patient, what’s my clock-out time at an 85% target?”
Given inputs
- Base 1:1: 330 min
- Concurrent: 30 clock min, 2 patients
- Crediting model: Full (× N)
- Target: 85%
Result
- Credited min: 30 × 2 = 60
- Adjusted billable: 330 + 60 = 390 min
- Total span: 390 ÷ 0.85 ≈ 459 min (7.6 hrs) from start time
Same session, split crediting instead
“My facility uses split crediting rather than full credit for the same 30-minute concurrent block. What’s the impact of that?”
Given inputs
- Base 1:1: 330 min
- Concurrent: 30 clock min, 2 patients
- Crediting model: Split (net unchanged)
- Target: 85%
Result
- Credited min: 30 (unchanged from clock time)
- Adjusted billable: 330 + 30 = 360 min
- Total span: 360 ÷ 0.85 ≈ 424 min (7.1 hrs) — about 35 fewer minutes worked than the full-credit example above
45-minute group session, 4 patients, custom 1.5× factor
“If I had a 45-minute group session with 4 patients, and my facility uses a custom 1.5× factor, how does that affect things?”
Given inputs
- Group: 45 clock min, 4 patients
- Crediting model: Custom, factor 1.5
Result
- Credited min: 45 × 1.5 = 67.5
- Outcome: The custom factor ignores patient count entirely — it applies the same multiplier whether the group has 2 or 6 patients, unlike the full-credit model.
Common mistakes & edge cases
Where concurrent and group minute crediting gets miscounted.
Assuming concurrent minutes automatically double
Full credit only applies if that’s how your facility’s policy actually works. If your facility uses split or custom crediting instead, defaulting to “× 2” for every concurrent session overstates adjusted minutes and produces an unrealistically early clock-out time.
Confusing group and concurrent definitions
Concurrent generally refers to two patients doing different activities within the same clinician’s sight, and group generally refers to two to six patients doing similar activities together. Mixing the two up can lead to the wrong patient count or the wrong billing category.
Ignoring the SNF combined minutes cap
Under PDPM, concurrent and group minutes are limited together to no more than 25% of therapy received for each discipline. Relying on concurrent/group crediting without checking this cap can produce a plan that doesn’t reflect what’s actually billable for a Part A resident.
Applying SNF concurrent rules to Part B billing
For Medicare Part B PT/OT, CMS describes simultaneous treatment of two or more patients with divided attention/shared instruction as group therapy (97150). Do not carry an SNF concurrent-therapy rule into Part B without checking the applicable billing guidance.
Treating SLP group rules the same as PT/OT
For speech-language pathology, group-treatment coding and coverage can vary by setting and MAC. ASHA identifies CPT 92508 for specified speech/language/voice/communication/auditory-processing group treatment and advises checking the applicable LCD for other restrictions or uses.
Crediting models compared
The same 30-minute, 2-patient concurrent block credited three different ways.
| Full (× N) | Split (÷ N) | Custom Factor | |
|---|---|---|---|
| Formula | Clock min × patient count | Clock min, unchanged | Clock min × your factor |
| Depends on patient count | Yes | No net change | No |
| 30 min, 2 patients → credited | 60 min | 30 min | Depends on factor (e.g. 45 min at 1.5×) |
| Best for | Facilities that count each patient’s full time separately | Facilities that treat the clock time as a single shared block | Facilities with their own internal weighting |
Concurrent Therapy Productivity Calculator FAQ
Generally speaking, “concurrent” describes treating two patients at the same time while both are in your line of sight, doing different activities. “Group” typically refers to two to six patients working together on similar or identical tasks.
No — it depends entirely on how your facility and payer credit that time. That’s why the crediting model is a setting here rather than a fixed rule; choose full, split, or custom to match the actual policy your facility uses.
Combined concurrent and group minutes under PDPM are limited to no more than 25% of the therapy received for each discipline during the PPS stay. Confirm your current facility’s policy — the flag on this page is a heads-up, not a compliance assessment.
For Medicare Part B PT/OT, CMS describes simultaneous treatment of two or more patients with divided attention or shared instruction as group therapy and uses 97150 in its billing scenarios. Check the current payer guidance rather than applying SNF concurrent rules to Part B.
Speech-language group-treatment coding and coverage can vary by setting and Medicare Administrative Contractor. ASHA identifies CPT 92508 for specified speech/language/voice/communication/auditory-processing group treatment and recommends checking the applicable LCD for restrictions.
Whichever one matches how your facility’s productivity system actually counts that time. If you’re unsure, that’s a question for your rehab manager or billing lead — not a guess.
The calculator behaves exactly like a standard start-time productivity calculator, using only your target and 1:1 billable minutes, with no concurrent or group math applied.
Full credit multiplies the clock minutes by the number of patients seen at once, while split credit leaves the raw clock time unchanged — so the same session can add anywhere from one patient’s worth of minutes up to N times that, depending only on which model your facility uses.
